I am planning to upgrade my unmolested 1978 Khorns in the next week or so. I want to document the changes in a thread along with listening impressions. I'd like to use this thread for some suggestions from you Klipschites, then start a new thread for the actual changes. I have some questions, then I'd like to listen to your ideas. Comment on or critique anything you want. I took out all the other speakers in the living room weeks ago to get used to the the Khorn sound in Stereo mode. My other choice would be Pure Audio, meaning no audio processing by the Onk AVR. Onkyo TX-NR 717, bought in 2014. The 717 has basic Audyssey, 3 listening positions. It will set distances and trim level relative to reference, which usually means -12 db. I have disabled Audyssey and set both L/R to 0 trim. I could re-run Audyssey to get some baseline info. The Upgrade: I will be getting some Crites A/4500 crossovers and I will pull the Type AA. This means I can't use the stock K-77's. I will using some SEOS 12" horns and Denovo DNA-360 compression drivers I already had from another project. This will not be the same as a standard Crites A/4500 with the usual CT-120 or CT-125 tweeters. I don't want to change two variables at one time but I don't think I have much choice. Your opinions? I would like to put the new horn on the tophat, then move it front to back to experiment with some time alignment. And finally I was wanting to try putting some damping materials on the tophat to see if I could hear difference in reflection by using carpet, towel, maybe some foam sheets. Other suggestions?
Built by Mr. Crites. I unscrewed the components and pulled them off the board as one. Veneered the stock Cedar boards in Tigerwood, lacquered them and screwed everything back on. Wanted to match the wood to a La Scala project I was working on. Replaced the tweeter cap with the new Jantzen Alumen Z-CAP made for tweeters and mids in passive networks. See the website if you like. The boards don't make them sound any better of course but they look nice and are unique. The Jantzen caps were $75.00 for the pair. They are new with very few hours on them but have made a nice change in the high end. The A/4500's are $230.00 a pair new. I will leave in the Jantzen caps and toss in the Sonicaps it came with. $180.00 including shipping and PayPal fees.
